self.view 的不当操作造成死循环

如题，在创建ContentView的时候，例子如下

NSString *viewClassName =  NSStringFromClass([self class]);
viewClassName = [viewClassName stringByReplacingOccurrencesOfString:@"Controller" withString:@""];
Class viewClass = NSClassFromString(viewClassName);
if ([viewClass isSubclassOfClass:[UIView class]]) {
    id currentView = [[viewClass alloc] initWithFrame:self.view.bounds];
    self.baseView = currentView;
    //千万不要用self.view = currentview.
    [self.view  addSubview:currentView]; 
   }
